Correct. Usually they are looser for the militarily as they know for sure what their health is, how good a shape they are in, that they have been vaccinated and where they have been and what they have been doing.
These are all things that are unknown for civilians.
And of everyone they have the most chance of not being infected, of recognizing when they might have been infected, and of recognizing the signs of infection and of promptly getting treatment.
These are things that a civilian might or might not do.
The rule are therefore backwards.
Not at all, the rules make total sense for the military, the military is more concerned about taking itself out through infectious diseases, not less so.
